Radish Taste Test

Well I should have taken a photograph, but didn't. Pulled two of the black radishes only to discover one was white and the other grey. They were long and slim, about the length of my hand and and about a broad as a finger. After a clean under the tap a taste test of the grey one suggested it was completely tasteless - a good bite revealed this was not the case. This must have been the hottest radish I ever ate, after a few seconds I was gaping for water. The white radish was not as hot but still excellent.
